Why is it impossible to override a getter-only property and add a setter? [closed]

Answer 1

Solution for only a small subset of use cases, but nevertheless: in C# 6.0 "readonly" setter is automatically added for overridden getter-only properties.

public abstract class BaseClass
{
    public abstract int Bar { get; }
}

public class ConcreteClass : BaseClass
{
    public override int Bar { get; }

    public ConcreteClass(int bar)
    {
        Bar = bar;
    }
}
